Goldman Sachs reiterates Buy on Siemens Energy; mid-term Gas Service targets may strengthen growth visibility

Overview

This report is Goldman Sachs' company research on Siemens Energy, with a core focus on the Gas Service business. Goldman Sachs believes global power demand is entering a capital expenditure supercycle driven by data centers, manufacturing reshoring, electrification, and energy security. Combined with the replacement of aging coal and gas assets and increased system intermittency from renewables, Gas Service has room for sustained improvement in equipment orders, service revenue, pricing, and margins.

Core views

Goldman Sachs reiterates its Buy CL rating and €212 target price on Siemens Energy. The core views are: first, Gas Service accounts for about one-third of group revenue, with both backlog and order quality improving significantly; second, the gas turbine market has shifted from previous overcapacity to supply tightness, allowing Siemens Energy to expand on its existing capacity base while maintaining a relatively short payback period; third, about half of FY2030 revenue is expected to come from Service, with the service business benefiting from new installations, nuclear life extensions, higher load factors, and longer operating lives for gas-fired power plants; fourth, FY2030E EBITA is 6% above consensus expectations, with valuation at about 6x 2030E EV/EBITDA and improving growth visibility.

Analysis framework

The report combines top-down power demand analysis with bottom-up business breakdowns: it first analyzes global power demand, AI and data center capital expenditure, coal retirements, replacement of aging gas assets, and renewable intermittency, then drills down to gas turbine orders, capacity, pricing, service revenue mix, and Gas Service margins; it also compares the positioning of Siemens Energy, GE Vernova, Mitsubishi Heavy Industries, and engine manufacturers in a supply-constrained environment.

Methodology notes

• Industry supply-demand analysisPower demand supercycle framework

  Uses data centers, manufacturing reshoring, electrification, coal substitution, and grid stability needs to explain rising demand for gas-fired power generation equipment.

  The report argues that the power sector is entering a capital expenditure supercycle, and that gas turbine demand comes not only from AI data centers, but also from asset replacement, energy security, and grid backup capacity.

• Business breakdownOEM and Service revenue split

  Breaks Gas Service into new equipment sales and service revenue, evaluating pricing, volume, post-installation services, and transactional revenue separately.

  FY2025 Gas Service revenue is about €12bn, of which around 34%-35% comes from OEM new equipment and around 65%-66% from Service; by FY2030E, about 50% of revenue is expected to come from Service.

• Earnings forecastFY2030 mid-term earnings bridge

  Derives FY2030E EBITA through revenue CAGR, margins, backlog, pricing improvement, and service revenue expansion.

  Goldman Sachs forecasts Gas Service revenue CAGR of 14% in FY2025-30 and FY2030E Gas Service EBITA of €6.2bn, with an EBITA margin of 26%.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• Siemens Energy (ENR1N.DE)

  Core covered name, benefiting from margin improvements in Gas Service, Grid Technologies, and Gamesa.

  Strengths

  Expanding Gas Service backlog, improved pricing environment, high service revenue mix, and better FY2030 earnings visibility.

  Weaknesses

  Part of the growth depends on continued realization of AI and data center power demand, and gas turbine capacity expansion could alter the supply-demand balance.

  Comparison

  The report cites GE Vernova and Mitsubishi Heavy Industries as major gas turbine peers, while engine manufacturers such as Cummins, Caterpillar, INNIO, and Wartsila may capture some substitute demand if gas turbine delivery cycles lengthen.

  Risks

  End-demand growth, energy intensity, and cost for AI remain uncertain; if market demand slows or too much new capacity is added, pricing and order quality could come under pressure.

• Gas Service

  Siemens Energy's key growth and earnings driver.

  Strengths

  Accounts for about one-third of group revenue, with FY2025 revenue of about €12bn; orders and backlog have risen significantly, and service revenue provides a longer cycle and higher visibility.

  Weaknesses

  Growth in both new equipment and service depends on continued additions of new installations, asset life extensions, and higher load factors.

  Comparison

  Compared with pure equipment sales, Service can generate more stable revenue through long-term maintenance, upgrades, repairs, and service agreements.

  Risks

  New gas-fired power plant plans, nuclear life extensions, the pace of coal phase-out, and customer capital expenditure may fall short of expectations.

• Grid Technologies

  Another source of long-term growth and margin improvement for the company.

  Strengths

  Benefits from grid capital expenditure, power transmission, and grid stability demand.

  Weaknesses

  The report is not focused on this segment, with fewer detailed earnings bridge discussions.

  Comparison

  Together with Gas Service, it reflects the power infrastructure investment cycle.

  Risks

  Project execution, supply chain, and grid investment timing risks.

• Siemens Gamesa

  Margin improvement is the third driver behind Goldman Sachs' positive view on group earnings expansion.

  Strengths

  If execution improves, it could contribute to group margin recovery.

  Weaknesses

  The wind power business has historically faced execution and profitability pressure.

  Comparison

  Compared with Gas Service, Gamesa has lower certainty in the report.

  Risks

  Wind project execution, cost control, and market competition risks.

Impact & implications

From an investment perspective, the report positions Siemens Energy as a core beneficiary of the power-demand supercycle and tight gas-fired power generation supply. If the company announces higher or clearer FY2030 mid-term targets with its FY results, the market may further raise long-term expectations for Gas Service revenue, margins, and cash flow, and assign a higher premium for growth visibility.

Risks

• Long-term AI and data center demand, energy intensity, and cost remain uncertain.
• If gas turbine capacity expansion exceeds real demand, supply-demand conditions could loosen again and bring pricing pressure.
• Conversion of backlog into revenue and profit depends on project execution, supply chains, delivery cycles, and customer payment capability.
• Coal retirements, replacement of gas assets, and new gas-fired power plant plans in Germany and Asia may be affected by policy, permitting, and energy transition constraints.
• Engine manufacturers and other alternative power generation technologies may divert part of data center demand when gas turbine supply is tight.
• Margin recovery at Siemens Gamesa and project execution at Grid Technologies may still affect delivery of overall group earnings.

What to watch

• Whether the company releases new FY2030 mid-term targets in its FY results, and whether those targets are above market expectations.
• Guidance for Gas Service FY2026 and FY2030 revenue growth, EBITA margin, and service revenue mix.
• Changes in gas turbine orders, reservation agreements, customer prepayments, and backlog duration.
• Whether data center power demand and hyperscaler capital expenditure in the United States, Europe, and the Middle East continue to be revised upward.
• Progress of Germany's 11GW gas-fired power plant tender, Saudi Arabia's 30GW target, South Korea's roughly 15GW gas potential, and Taiwan's more than 30GW gas target.
• Pricing, capacity expansion, and order changes at GE Vernova, Mitsubishi Heavy Industries, and engine manufacturers.
• Delivery against the roughly €8bn FY2026 free cash flow guidance.
